Bungie co-founder Alex Seropian has resigned from his post as Disney's SVP and general manager of core games.
Disney confirmed the news to Gamasutra, and informed the site that Seropian would be replaced by Bill Roper, who has previously held roles as VP of Blizzard North, and VP of the Marvel franchise for Disney.
Seropian had held the position since September 2009. He was also CEO and founder of Wideload Games and Bungie Studios. There is no news on his future career plans.
The news follows the release of Disney's Q1 2012 financial results, which showed decreased revenues for its Interactive Media division.
